Is it possible to extend a class dynamically?

Question

I have a class which I need to use to extend different classes (up to hundreds) depending on criteria. Is there a way in PHP to extend a class by a dynamic class name?

Answer 1

I have an idea so simple, you can try

class A {} 
class B {}
$dynamicClassName = "A";
eval("class DynamicParent extends $dynamicClassName {}");

class C extends DynamicParent{
   // extends success
   // Testing
   function __construct(){
        echo get_parent_class('DynamicParent'); exit; //A :)
   }
}
